Definitions

  • This invention relates to a capsule for making beverages.
  • those capsules comprising a body and a lid which closes the top of the body.
  • a powdered food substance for example coffee powder
  • the body comprises a lower wall and a lateral wall, and which inside them have a filter interposed between the lower wall and the lid for separating the powdered food substance at least from a relevant portion of the lower wall.
  • capsules suitable for use in beverage making systems in which the capsule is pierced at the lid, to allow the injection of water (which may be pressurised) into the capsule itself, and at a central portion of the lower wall (the relevant portion), to allow dispensing to the outside of the capsule of the beverage produced by the interaction of the water with the powdered food substance.
  • the filter is positioned close to the lower wall so that the capsule can contain a larger quantity of powdered food substance between the lid and the filter.
  • the filter is instead substantially made of a flexible material such as paper, fabric, non-woven fabric, etc.
  • capsules which on the inside have a flat fabric filter, fixed to the lower wall, which is permeable to the beverage and at the same time can retain the powdered food substance.
  • Such capsules are suitable for use with beverage making systems in which the element for piercing the lower wall penetrates inside the capsule, remaining there for the duration of beverage dispensing which, advantageously, takes place through channels made in the piercing element itself.
  • the filter may be damaged, for example cut by the piercing element, although the outflow of powder is substantially prevented by the interference between the piercing element and the edges of the filter surrounding the cut made by it.
  • capsules such as those described above are not compatible with all beverage making systems and in particular they are not compatible with some capsule lower wall piercing methods.
  • the piercing element in systems in which the piercing element is particularly sharp, or in systems in which the thrust applied by the piercing element on the lower wall is particularly great, the piercing element can easily cause a tear in the filter.
  • the technical purpose which forms the basis of this invention is to provide a capsule for making beverages which overcomes the above-mentioned disadvantages.
  • the technical purpose of this invention is to provide a capsule for making beverages which is equipped with a low cost filter and which is suitable for use according to the various methods for piercing or cutting the lower wall.
  • Figure 1 is a vertical section of a first embodiment of a capsule in accordance with this invention.
  • Figure 2 is a vertical section of a first alternative embodiment of the capsule of Figure 1 ;
  • Figure 3 is a vertical section of a second alternative embodiment of the capsule of Figure 1 ;

  • the numeral 1 denotes in its entirety a capsule for making beverages in accordance with this invention.
  • the capsule 1 in accordance with this invention contains at least one powdered food substance which can be extracted by passing water through it to make a beverage.
  • the powdered food substance for example powdered coffee, can be extracted for example by infusion or is soluble to make a beverage such as coffee or tea, infusions, soups, etc.
  • the capsule 1 may if necessary be suitable for allowing extraction of the powdered food substance, for example coffee, by passing pressurised water through it, for example for making an espresso coffee.
  • the capsule 1 comprises a substantially cup-shaped body 2 comprising a lower wall 3 and a lateral wall 4.
  • the lower wall 3 of the capsule 1 substantially extends in a circular fashion and the side wall 4 extends from it with a shape that to a first approximation is frusto-conical, the upper part of it ending with an edge 5 located on the opposite side to the lower wall 3.
  • a lid 6 is fixed to the capsule 1 body 2 at the edge 5 and closes the top of the capsule 1 body 2. Between the lid 6 and the inner surface of the capsule 1 body 2 there is a chamber 7 for containing the powdered food substance.
  • the capsule 1 is therefore suitable for insertion in a beverage making system which advantageously comprises a housing in which the capsule 1 can be positioned for use for making a beverage.
  • the system in the substantially known way, comprises injection means for injecting water into the capsule 1 and extraction means for extracting the beverage form the capsule 1.
  • the capsule 1 lid 6 is pierceable to allow the injection of water into the chamber 7, and the lower wall 3 is pierceable, at a central portion 8 of it, to allow extraction of a beverage from the capsule 1. Consequently, the beverage making system suitable for using a capsule 1 in accordance with this invention will have the injection means associable with the capsule 1 lid 6 and the extraction means associable with the capsule 1 lower wall 3 and in particular with a central portion 8 of the lower wall 3.
  • the lower wall 3 of the capsule 1 according to this invention is therefore suitable for penetration by a piercing element, which refers to any element, substantially of the known type, able to pierce, cut or tear, for example a spike or a blade, fixed or mobile.
  • the capsule 1 also comprises a filter 9 at least mainly made of a layered sheet of flexible material positioned inside the chamber 7 close to the lower wall 3.
  • the filter 9 separates the powdered food substance at least from the central portion 8 of the lower wall 3, and is permeable to the beverage, at the same time preventing the passage of powdered food substance.
  • the filter 9 may therefore separate the powdered food substance from even a limited portion of the lower wall 3, substantially corresponding to the portion of lower wall 3 delimited by the substantially annular portion with which the filter 9 is associated.
  • the filter 9 separates the powdered food substance substantially from the entire surface of the lower wall 3, the filter advantageously being associated with a substantially annular and marginal portion of the lower wall, close to the lateral wall 4, or at the lateral wall 4 itself.
  • the filter 9 may separate the powdered food substance even from a portion of lateral wall 4 adjacent to the lower wall 3 if it is fixed to the body 2 at the lateral wall 4.
  • the term flexible material refers to a material which is neither rigid nor semi-rigid, for example a plastic material, although it refers to a material which can be folded, rolled up on itself, folded over itself, and if necessary is soft and can have various degrees of deformability and has a texture such as paper, fabrics with various weaves and even polymers, a non-woven fabric, a thermoformable fabric, a plastic film, etc.

  • the filter 9 may. be in contact with the lower wall 3 only at several points, as shown in Figures 1 , 3, 4 and 6, or it may rest on the lower wall 3 substantially adapting to it, except for on the central portion 8 ( Figures 2 and 5). Therefore, advantageously, the filter 9 extends substantially on the entire surface of the lower wall 3 and rests on the latter except on the central portion 8 where there is the projection 10.
  • the filter 9 may in various ways be limited to covering more limited portions. For example it may cover just more than the central portion 8 only of the lower wall 3 which, during capsule 1 use, will be penetrated by a piercing, cutting or tearing element (embodiment not illustrated).

  • This invention brings important advantages.
  • the capsule according to this invention allows the use of a filter composed of an inexpensive sheet of flexible material, for example paper, although it can be used according to various methods for piercing or cutting the lower wall.

Abstract

On décrit une capsule (1) contenant une substance alimentaire en poudre qu'on extrait en faisant passer de l'eau à travers celle-ci pour produire une boisson. La capsule comprend un corps (2) présentant une paroi inférieure (3) et une paroi latérale (4), et un couvercle (6) fixé au corps (2). Le couvercle (6) et une partie centrale (8) de la paroi inférieure (3) peuvent être percés respectivement pour permettre l'injection d'eau dans la capsule (1) et l'extraction d'une boisson de celle-ci. Un filtre (9) est placé entre le couvercle (6) et la paroi inférieure (3), à une position proche de cette dernière. Le filtre est perméable à la boisson et retient la substance alimentaire en poudre. Il est au moins principalement constitué d'une feuille en couches d'un matériau souple fixé au corps (2), qui isole la substance alimentaire en poudre au moins de la partie centrale (8).
